WATER-Moron.

To all wwm 'it may concern:

Be it known that I, HARRY W. Mazara, a States, residing 'at Springfield, in the. county of Clark and State of Ohio, have invented certain new and useful Improvements in Water Motors, of

ence being drawings. l

This invention relates to water motors and the obj eetof the invention is to provide 'an oscillatin. water motor, the construction of which ,wi 4be very simpleand of such a character as to Afacilitate the assembling-of had therein to the accompanying the .machine in the course of itsl 'manufac-- dure; which 'will be provided with means for.

fpositively, quickly' 'and simultanemisly re` versing 4the valves; andwhieh fwill have the 'convenient and easily accessible sition.

With"these vobjects iii-view' my invention consists-incertain novel features and in cer'-,

tain combinations and .arrangements of partsV hereinafter v t bedescribed, and then more particnlarlygPQl-L lutintheclaims.v Inthe-aeeompaf.. .is a venian sectorial view raken centrally through 'a ymotor embodying my invention;

lFigl 21s atransversejsectional view',.takcn direction'ofthe'arrows; and'Fig. 3 1s a s ectional-detail'view of-' the valves.' Q .fzln these drawingsl have illustratedl one "embodiment -of [my 'invention and haveshown the vsame as consisting of a cylinder comprising a' ibody p ortionl having its opposite ends closed by cilinder heads 2 which are connec'tedlone'tto t e1- other bymeans of carried by each cylinder head. .Each cylinder head 2'is provided' withal centralopening which vforms a'bearing for ,the motor shaft 5 which extends beyond. the cylinder heads 2 and has one end adapted to be' con-- nectedto the mechanisin-tQ- be operated.

Suitable stnfiingvl boxes are *formed 'about/theVV shaft 5-'at eac end thereofj'by providing e'achof vthe cylinder heads with -outwardly .extending roundingshaft and'- are iadaptedto receive a suitable Specification of Letters Patient. Application mea my a, 190e. serial No': 493,447.

which the following is aspeciiication, refer' means of a gland 8 which ts snugly about the adjacent end of theshaft and is screw- -threaded into the boss 6. At the lower en d of the shaft 5 the land is of ordinary construction, but at le upper end thereof it 'comprises a part of the housing 9 into which the upper end of the shaft 5 extends and Whiclris provided-with a suitable nipple .or connection 10 for connecting the same with the inlet ipe, and a'second nipple or connection 11.4 or connectingthe same with the outlet pipe. The lower portion of the hous- `the packing 7 which Stung'box.' 1 A' plst'on, 1% is rigidly secured to and preferably formed integral with the shaft 5. -This piston is provided with two chambers chambers -are forme y casting, or-other\vise .-forming, the piston212 the same by ahorizontal partition 1 5 arranged substantialfly' midway ges thereof and thereby dividin the samelnto two chambers,- one AAof whic rcor'nprisesj'the inlet chamber and' the other the outlet chamber. chambersl and 14' isprovided in the o site sides thereof with openings l1G an 17, ..1iespectively, whichare controlled by valves 18 and 19 and by means of which the chamtion with the interior of `the `cylinder 1 on either side of :the piston.' These valvesare so arranged that, when the valves` are both movedA to thelimit' of their move* nent in one dircct-ion,'the lopeningl of one chambcr'iu one face of the piston' will be open-aud the corresponding opening of the other rluuuber will beclosed. To this end the valves iu ofthe piston and are connected4 b v winged guides 20, while the valves 1S) 'are formed in va sinf'le piece and are mounted within the chamber, seating against the inner edges of the openings and` 'are provided at their outer. ends with winged lenc'ths ofthe valve men'ibcrs 1S and 19, 'with their respective guides, are substan- V tially the saine so that, when the valves have been movedwto the limit of their movement May 17, 1910.

ing 9'is screw-threaded to fit within the boss 6 and serves asa retaining plug or cap for Ais contained in the 13 `and 14` In. the1 present instance, these.

Ibetween the bersf13 and 11i-maybe placed -in communica-` --here shown of ordinary 'construction and are i the-upper chamber are seated ou the outside hollow and dividing Kruides 2l. The 1 the same direction, the outer. ends thereof -outlet 11.1 The lower compartment 23 of will extend .substantially the same distance fr m the f face of the piston on 'each.side

the cof. The chambers 13 and 14 are preferably eghpgeted'with the inlet and outlet by means p tion ,of some character shouldbe arranged of\ passages formed in theY motor shaft 5 and connected at' their outer ends to the outlet end inlet 1l and 10, respectively, and at their inner ends to the chambers 14 and 13, respectively.V In the Vpresent instance, I

.have provided these passages by forming the shaft hollow/and dividing the same into upper andlower compartments 22 and 23 by means of a. horizontal partition 24 forming a continuation of the partition which divides thehollow piston 12 into two' chambers. The'upper compartment 22 of the hollow shaft 5 1s in direct communication with theu'pper chamber 13 of the piston and the upper' end of the shaft opens into the housing 9 and is thus directly connected with the Y the hollov'r shaft 5 is in direct communication with the lower chamber 14 of the hollow piston and is .connected with the inlet 10 A by means of a conduit or pipe 25 which extendsL thrdngh housing 9 and .into the nipple 10 which forms=the inlet.4 Thus it n ll be apparent that, in the operation of the device, the water will-be admitted through the inlet passagecomprising the lower compartment of the shaft 5, through'the chamber 14 and one of the openings 17 into the cylinder and that ites'capes from the cylinder through one of the'openings 16. of the chamber 13 of the piston into the outlet passage comprising -the upper compartment 23 of the shaft and the pipe or conduit 25.; and that by this arrangement of the inlet and outlet passagesI vam enabled to lace the connections for the supply and exliaust pipes in a most cnvenient and easil 'c accessible position. It is obvious that, wh e I have described the upper'chamber of the piston and the upper compartment of the shaft as the outlet and the lower chamber of the piston and the lower compartment as the inlet, this arrangement could readily be reversed without interfering with the operation of the motor.

The piston `12 preferably has its three ges, which are 1n engagement with the a ls of the cylinder, concave, as shown at 27, and provided with a packing 28 'which is secured-thereto near the center of the edge of the piston by bolts 29, this packing following the contour of the concave edge ot' the piston and engaging the wall of the cylinder at two points only, thus materially re- `gitudinally of the shaft 5 and provided with staats' ducing the friction between the piston and the cylinder and at the -same time preventing theI passage of water between the "cylinder/l tweenthe s aft 5 and the wall of 'thlvfc'ylin-` der and 'has an inwardly extending Aor radially arranged partitionA 31 extending lonf l a packing 32 bearing against the *outer surface of the shaft and forminga water-tight joint between the shaft and the partition 31. The partition 31 Ais preferably provided with a longitudinal recess 33, which, in the pres# ent instance, is shown as irtending the-full' depth of the partition, in which the packingg 32 is secured. In order that the valves may be simultaneously and quickly reversed when the piston has reached onelimit of its movement I have movablymounted on the chord-4- wisel partition 30 two plates 34 extending longitudinally of the iston and o f a' length suihcient to engage bot f the valves mount- 'ed therein'..` These plates are supported in their normal positions by means of .springs 35 which are arranged'between the-lower sides of the plates 34l and 'theucho'rd-wise partition and are held against movement relatively to the plate 34 by means-f pins or projections 36, about; whichthe upper ends of the spring are tightlyl coiled. The

Aplates 34 are preferably pivotally mounted on the partition 30 ata point near the point of union of the chord-wise partition 30 and the radial partition 31,"this connec-l tion being 'preferably made by means -of pivot pins 37 which extend loosely through the inner ends of the mates 34 andA permit of a slight amount of lost motion or Wabbling movementin the plate, thereby enabling the same to adjust ltself to any slight irregularities Vin fthe lengths of the two valves and avoiding the .necessity for fine adjustmentsof these valves. The iston isarranged to move through an arco 180 degrees and the plates 34 are normally supported in such a position that, as `the piston approaches the lmitofits movement 1n one direction, one of thc plates will engage theV projecting ends of the valve members 18' and 19. 'lhe pressure of water against the valve members will tend to resist the movement of' the same and the valves will not be shifted until the springs 35 have been compressed toI a greater or less extent, and (he combined to overcome the pressure of the waterwhen the valves will be quickly shifted from one position to the other, thereby positively and Aaction et' the piston and spring is sufjicient the valves and the flow of the water, and,

consequently, reversing the direction of' movement of the piston. The plates 34 are provided with squared stops or shoulders 38Y adapted to engage the partition 31 and limit the upward movement of the vplates and pre-- ventV their being thrown into aninoperative position by the action of the spring The operation of the motor has been describcd'in connection with the descri tiolii of the several parts thereof and it will) be apparent 'that I have provided an oscillating motor, the construction of which is exceeding.y simple and is of such a character as to greatly facilitate the assembling of the motor, t being immaterial which is the upper and which is the lower end of the cylinder; the piston and the shaft fitting equallyl well when inserted from either side i` and -the bosses 6 being of the same'size. It will also be yapparent that I have so constructedthe piston as to materially reduce the friction caused bythe engagement between thc"pis' ton and the walls of the cylinder and that I have provided means for simultaneously, positively and quickly reversing the `positions of the valves, and, consequently, 'shifting the flow of water from one side ofthe piston to the other. vions that the detail construction and arrangement of the several parts of the motor are susceptible to a wide range of modification and I, therefore, wish ittobeunderstood that I do not desire to be limited'to the details of construction shown and. de-- scribed, for obvious modifications will occur to a person skilled in the art.
